I upgraded my early 2011, SSD equipped MBP to 10.8 on day one and have done multiple reboots with no problems. Tonight I turned on FileVault on my boot drive and BOOM! Blue screen cast.

FileVault does change the boot sequence so the suggestions of failing to load the colour profile seem reasonable. Not necessarily because of speed perhaps, but something about the re-ordered boot process that FileVault entails.

I did upgrade-install with FileVault off for the SSD and the issue was there.
Only re-login trick worked but it had to be applied on each boot...
Then I did reset SMC and PRAM, so far everything's fine here. Just and idea

I have the White MacBook from 2009 and now am having an this blue tint issue. I've tried shutting down the computer and then starting it back up and also going into the "display" options and nothing happened.

Interesting thing was when I opened my computer it said that there was an error and had to reboot (it rebooted before I opened my computer) and that I should send the error report - which I did.

But this is very annoying on the eyes. I hope someone can find a solution to this soon.

I just experienced this issue. When switching to the dedicated GPU on my Late 2011 MacBook Pro, I found that my screen had a blue tint to it. This was right after updating to the latest SMC update.

I reset the SMC, and all was well.

To reset the SMC on any Unibody MacBook Pro or higher -

1). Shutdown the Mac
2). Connect the MagSafe power cable
3). Press and hold the LEFT Option+Control+Shift keys on the built in keyboard
4). While still holding the keys above, press the power button in the top right corner of the Mac

While it doesn't look like you did anything, it actually did reset the SMC. After doing this, boot the Mac normally, and once booted to the desktop, see if that resolved the issue. If it didn't, the only other thing I can suggest is to reset the NVRAM

To reset the NVRAM -

1). Shutdown the Mac
2). Press and hold Command + Option + P + R on the built in keyboard
3). While still holding the keys above, press the power button in the top right corner of the Mac
4). Release the keys after you hear the startup chime for the 3rd time.

If that didn't resolve your issue, you may have a corrupted Color Profile, which can generally be resolved by restoring an old copy from a Time Machine backup. Restore an old copy of "Color LCD-00000610-0000-9CB7-0000-000004272DC0.icc" to /Library/ColorSync/Profiles/Displays/ , please note that your profile name may differ, but the "Color LCD" profile is the correct one for the built in display.
